GEORGE K. SMITH, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE I-I. C. STAVE IMPLEMENT COMPANY, OF SAME PLACE.: 1

SPECIFICATION 'forming part of Letters Patent No. 324,181, dated August 11, 1885. Application filed May i6, 18785. (No model.)

T0 all whom it may concern:

Be it known that I, GEORGE K. SMITH, re-j siding at Chicago, in the county of Cook and Siate of Illinois, and a citizen of the United States, have invented a new and useful Im-f provenient in Grinding-Mills, ot' which the following is a full description, reference being had to the accompanyingdrawings, in which- Figure l is .a plan, the hopper being re-` moved. Fig. 2 is a top view of the hopper, and Fig. 3 a bottom view of the same. Fig.. 4 is a plan of the metal frame. Fig. 5 is avertical section at line a' x of Fig. l, the hopper being shown. of the parts represented. Fig. 7 is a detail,l and is an elevation of the parts shown. Fig. 8 is a bottom view ofthe lowergrinder. Fig. 9 is a plan view of the lever P. Fig. l() isa vertical section at line y 1/ of Fig. 1, the hopper being shown.

parts being removed. and bottom view of the part shown.

is a top view and side view of thepart shown.

Fig. 14 is a top and side view of the part Fig. l5 is a side view of the master- Fig. 16 is a side view of the Inetal B is a metal frame secured to the frame A.`

This metal frame consists of an outer ring, arms b, and a central horizontal ported by the arms b.

d is a circular projection extending upward a short distance from c, which projection is somewhat smaller in diameter than c, so that the outer portion ofc forms a shoulder, e. The parts d and e have a small central opening, f, through which the spindle passes. This metal frame, consisting of the parts a b c may be east in one piece.

C is the master-wheel, consisting of a ring, g, having gear -teeth h on the inside, and arms t', carrying a `central ring,`j, which fits over d and rests on the shoulder e.

D is a disk having a central opening, k.

a, part, c, sup- Fig. 6 is a side elevation Fig. l1 is a sectional de-,ry tail taken at line .fr x of Fig. 10, some of the Fig. v12 is aside viewl Fig. 13y

posts extending up from the sweeps to which the animalsare to be attached.

G is the spindle, carrying at its upper end one of the grinders, n. The other grinder, o,

is, as shown, cast on the under side of thehopper H, which hopper is provided with a flange, p, which is bolted to ears upon the case F, as shown in Figs. 6 and 10. q is a delivery-spout.

I is a gear-wheel, and J is a bevel gearwheel.

I andJ are cast together and are secured upon the spindle G by means of a feather, so that the spindle can be moved up and down .without changing the position of the wheels r is a spring around the lower end of thev spindle G, and resting on a collar thereon.

' K K are two gear-wheels supported on pins on the frame B and engaging with the pinion I.

M M are two pinions connected with the hubs of the gear-wheelsK K', which pinions M M engage with the teeth 7L upon the inside of the master-wheel.

N is a bevel-wheel engaging with J, and is rsecured to ashaft, O, which shaft is supported in bearings s s.

P is a support and lever, one end of which passes through a slot in the post E, and is prevented from escaping therefrom by a pin, u. The other end of this lever passes through a long slot in the post E', and upon the outer end is pivoted a screw-threaded arm, o, which passes loosely through a hole in the bracket w, which is bolted tothe post E.

c is a hand-wheel on the top of the screwthreaded arm o. A portion of the lever P is spread out-or enlarged, as shown in Fig. 9, leaving an opening between the two sides b b.

c is asleeve having a trunnion on each side,

IOO

which trunnions rest in recesses in the upper edges of the parts b b.

d is a sleeve resting on the sleeve c. upper part ofd is eup'shaped, as shown.

c is a collar, the under side of which is provided with two slnall pins, j, which enter corresponding holes in d. The collar c is provided with a set-screw, The spindle passes through the parts c' d c. lt will thus be seen that the weight of the spindle is carried by the lever I through the medium of the lruunions on the sleeve e' which rest in the recesses in the side pieces, b b', 'ol' said lever. The sleeve e is prevented from any upward sliding movement on the spindle G by means of the sleeve d and collar e', the latter being securely held on the spindle by the set-screw The f, so that any upward movement ofthe lever P will cause the spindle G to be correspondingly raised. .lhe master-wheel rests upon the shoulder c, and the projection d serves the purpose of a center-pin. The disk D, which is secured to d, extends over the ring j and holds the master-wheel in place.

The spindle G has two bearings, one in the parts c d of the frame, the other in the bottom of the case F. It has no support at its lower end, as is usual, but it is supported by the lever P and by means of the sleeves c and d and collar e,vthe latter being held fast on the spindle by a setscrew. The position of these parts cd c on the spindle can be adjusted by loosening the set-screwj and then raising or lowering the spindle.

rlhe spindle which carries the grinding-disk a can be raised and lowered by means of the hand-wheel c', screw c, and lever l without throwing the spindle out of line, because the sleeves c d will accommodate themselves to the changed position of the lever 1I?. The lever P, sleeves c d', collar c', and trunnions and setscrews which carry the weight of the spindie also have a tendency to support the same at a point about midway between its two bearings, and cause it to run more steady than it otherwise would. The spring r acts upon the spindle, in addition to ils weight, to l'oree it down when the lever l is lowered, and also supports the pinion J.

In the drawings the two grindingdisks are shown a greater distance apart than they will be in actual use.

'lhrough the bevel-wheel N and shaft O power can be communicated from the mill to machinery driven through the shaft O. By loosening the collar iron this shaft O the pinion N can be disengaged from J, when desired.

It is not essential that the hopper and the top of the case F should be made together.

NVhat I claim as new, and desire to secure by Letters Patent, is

l. In a grinding-mill, the combination of the posts E E, carrying the upper grindingdisk and attached to or formed with the disk D, the spindle G, carrying the lower grindingdisk, the master-Wheel C, and the frame B, consisting of the ring a, arms b, and horizontal part c, substantially as described.

2. In a grndingmill, the combination of the main framev B, master-wheel C, disk D, posts E E', case F, spindle G, grinding-disks a 0, and lever P, adapted to carry the weight of the spindle, substantially as and for the purposes specified.

3. In agrindinglnill, the combination, with the posts E E', carrying the upper grindingdisk, o, and the spindle G, carrying the lower grindingdisk, il., of the divided lever P, pivotcd in one ofthe posts E E, sleeves c d', and collars e', substantially as described.

4. A grinding'mill comprising the supports E E', carrying the upper grinding-disk, the disk D, the spindle G, carrying the lower grinding-disk, the frame B, master-wheel G, pinion I, and bevel-wheel J, secured to spinf dle G, and bevel-whee1 N, secured to shaft O and meshing with wheel J, substantially as described.
